Abstract: 565,923. Feeding lengths of adhesive strips or tapes. KRUEGER, T. H. May 7, 1942, No. 6192. Convention date, May 13, 1941. [Class 18] Apparatus for serving measured cut-off sections from a continuous tape or strip of tacky material 13, Fig. 1, comprises a feeding and delivery element 15 having at least two supports 30 spaced from one another in the longitudinal direction of the strip and adapted to contact the tacky surface so that the strip adheres thereto, the strip-engaging surfaces being of sufficient contact area to retain a severed section of tape by adhesion to assure its controlled delivery, but of such limited area that the section can be readily detached, the element 15 being movable in a direction to withdraw the strip material 13 from the roll 12 and present it in a position for severance and subsequent removal of the severed sections. The feeding and delivery element 15 is in the form of a reel having a number of tape supports 30, Fig. 3, spaced about its circumference. The cross-members 30 are arranged in pairs so as to support the tape firmly and permit it to be cut by knives 50 mounted on spring-controlled bell-crank levers 51, 55 pivoted at 52 and actuated by rollers 56 riding on a cam surface 60. The reel is provided with three handles 34 and is moved successively through 120 degrees. The tape may be severed at each pair of supports 30. Alternatively, if longer pieces are desired, some of the knives 50 may be rendered inoperative by means of stop screws which serve to disengage the corresponding rollers 56 from the cam 60. In a modification, a strip or strips of tacky tape 131 from one or more rolls 120, mounted between cradle bars 122, Fig. 8, are fed to a feeding 'and delivery reel 130 having supporting members 141 comprising spaced plates or bars 142. The reel is rotated by a crank acting through a pawl 165 pivoted on a disc 163 under the action of a spring 168 and engaging the ends 147 of the members 142. Stops may be provided to regulate the throw of the crank handle and reverse rotation is prevented by a weighted dog 170 pivoted at 171. Knives 182 are mounted on an arcshaped carrier 175 slidable transversely on rods 113, 114 to cut the tapes when the parts are in register. The proper disposition is ensured by the setting of a stop and by a pilot plate 187 mounted at the upper end of the carrier plate 175.

Abstract: 1,134,213. Coated sheet material. COURTAULDS Ltd. 15 Feb., 1966 [16 Feb., 1965], No. 6588/65. Addition to 1,087,867. Heading B2E [Also in Division C3] A gas permeable laminated sheet is produced by forming a solution of a block copolymer having segments of a polyamide and a polymeric substance having a melting point of less than 80C, the solution also containing a dissolved elastomer, applying the solution to a coherent fibrouslayer, precipitating the copolymer from the solution to form a gel containing residual solvent and reducing the solvent content of the gel at a temperature below the glass temperature of the gel, whereby the copolymer tends to aggregate in interconnected micelles, generating pores in the gel. The solvent is preferably an aqueous solution of alkali metal or alkaline earth metal thiocyanate containing ethyl or methyl alcohol but other salts e.g. alkaline earth metal halides, ZnC1 2  and LiBr, are useful. The elastomer may be a copolymer of at least two acrylates, an acrylonitrile-alkyl acrylate copolymer, the alkyl group containing at least two carbon atoms, or an acrylonitrile-butadiene copolymer containing at least 40% of acrylonitrile units. The elastomer may be formed in situ in the salt solution which may contain the block polymer by copolymerizing acrylate with another, or with acrylonitrile. The polyamide may be a homo or random copolymer e.g. nylon or a copolymer of caprolactam and hexamethylene adipamide salt. The elastomer segment of the block polymer may be a polyether carrying terminal isocyanate groups, which may be reacted with an amine terminated polyamide in the presence of the solvent so that the copolymer is formed in solution. The weight ratio of the block copolymer to the elastomer may be between 2:3 and 3:2. The solution may be applied by doctor blade to a dense felt of crimped nylon bonded with an elastomer and the coated felt is washed with water to remove the thiocyanate.

Patent GB-793737-A (GB)
Title: Mineral oil compositions
Inventor: SCOTT JAMES
IPC: C10L1/22
Filed: 1956-03-02
Abstract: An oil composition for spreading on aqueous systems to prevent foaming comprises a major proportion of a mineral oil and minor proportions each of an alicyclic amine salt and an ester or partial ester of a dihydric alcohol and a monocarboxylic acid. The mineral oil preferably has a viscosity of 50 to 500 SUS/100 DEG  F., e.g. kerosine, spindle oil, gas oils and heavier mineral oils. The preferred amine is cyclohexylamine and the preferred acids used to form the amine salts are C10-24 fatty acids. Suitable esters are esters of C10-24 fatty acids especially hydroxy acids, e.g. ricinoleic acid and glycols, including 1.2- and 1.3-glycols and polyglycols, an example being polyethylene glycol di-tri-ricinoleate. The preferred proportions are 0.01 to 10 per cent wt. of amine salt and 0.001 to 5 per cent wt. of glycol ester. 5 to 10 p.p.m. are said to be effective for foam inhibition in aqueous systems.  An example comprises 98.3 per cent wt. mineral oil of 100 SUS/210 DEG  F., 1.5 per cent wt. cyclohexylamine oleate, and 0.2 per cent wt. polyethylene glycol di-triricinoleate.  According to the Provisional Specification the amine salts may be those of primary, secondary or tertiary amines of aliphatic, cyclic, heterocyclic or aromatic compounds, e.g. mono-, di- or tri-ethanolamine, morpholine, cyclic glyoxalidines or imidazolines.  The esters of dihydric alcohols may be replaced by any ionic or non-ionic oil-in-water emulsifier, e.g. oil-soluble petroleum sulphonates or fatty acid esters such as mono- or polyesters of C10-24 fatty or hydroxy fatty acids and monohydric alcohols or glycerol (e.g. polyglycerides).ALSO:The formation of foam during the treatment of sewage is inhibited by the addition of a composition comprising a major proportion of a mineral oil, a minor proportion of an alicyclic amine salt and a minor proportion of an ester or partial ester of a dihydric alcohol and a monocarboxylic acid.  In an example a sewage tank having a surface area of 25,000 sq. ft. in which sewage resides for eight hour periods while air is bubbled through at 100 to 70,000 cubic feet per minute is treated with between 5 and 10 parts per million of a composition comprising (by weight) 98,3 per cent mineral oil (100 SUS/210 DEG F.), 1,5 per cent cyclohexylamine oleate and 0,2 per cent polyethylene glycol di-tri-ricinoleate.  According to the Provisional Specification the amine salts may be those of primary, secondary or tertiary amines of aliphatic, cyclic, heterocyclic or aromatic compounds, e.g., mono-, di- or tri-ethanolamine, morpholine, cyclic glyoxalidines or imidazolines.
